Now supports two-step authentication that requires token authentication (OTP) or email authentication after passing the conventional ID & password.
You can set it from the "Address" tab > "Account information in use" > "Two-step verification".
To enable "Two-Step Verification", you must first set up a "Recovery Address".
Currently, the following authentication methods are supported.
・When using two-step email verification, a verification code will be sent to your "recovery address".
・Token authentication (OTP)
Use an app that supports RFC 6238 (TOTP) such as "Google Authenticator".
When setting up for the first time, register with the TOTP app using a QR code or private key, and from next time onwards, authenticate using the token generated with the TOTP app.
If two-step verification is enabled, two-step verification will be required at the following times.
・When logging in (excluding logging in from a linked ID)
・When deleting an account ・When disabling two-step verification
